Permission denied: '/opt/prom2teams/config.ini'

Description

I get an error on startup when mounting a custom config file readonly in docker.

NOTE: We are not allowed to have config files which are not readonly. It's a very bad idea anyway to have configuration files that are writable. This is very special to prom2teams and I've not seen any other software that needs this.

Steps to Reproduce

1. Run idealista/prom2teams:4.0.0 docker image using docker-compose

Expected behavior:
Service should start

Actual behavior:
Service crashes with following error:

PermissionError: [Errno 13] Permission denied: '/opt/prom2teams/config.ini'
Traceback (most recent call last):
  File "/opt/prom2teams/replace_config.py", line 13, in <module>
    with open('/opt/prom2teams/config.ini', 'w') as file:

Reproduces how often:
Always

Environment

• The release version/s you are using: 4.0.0
• OS: Debian buster
• Others: docker-compose version 1.29.2

Up !
I had to go back to release 3.3.0 because of this issue :)

[abdennour]

Same issue in Openshift 4.x !
Please expedite reviewing #316

[santi-eidu]

New release 4.2.1 should fix the error.

[kevin-sedimentum]

Can confirm. This is fixed in version 4.2.1
